We have LVDS and HDMI display connected to imx6 board and both displays are showing same contents.
But we want to see different content on these displays. My bootargs is like that:
setenv bootargs console=ttymxc0,115200 video=mxcfb0:dev=ldb,0,if=RGB24,bpp=32 video=mxcfb1:hdmi,1920x1080M@60,bpp=32 video=mxcfb2:off video=mxcfb3:off vmalloc=256M androidboot.console=ttymxc0 consoleblank=0 androidboot.hardware=freescale cma=384M androidboot.selinux=disabled androidboot.dm_verity=disabled no_console_suspend=1
Could you please help us about this issue?
Which board are you using?
We are using our custom board, but we have inspired by Sabre board.
Unfortunately, this is not related with the bootargs. The only solution that I could find was through an app. In the below link, you can find more information related to this:
